I know that CDP model can effectively give results for SFRC, but is there any way I model Steel fibres seperately and embed in concrete and observe its behaviour for different orientations?If yes, What parameters or model do I need to consider?
Dear Laiba Ayub
Please tell me why do you want to model steel fibers separately? Because, when using FEM, we don't model aggregate in concrete! The same scenario applies to modeling steel fibers.
However, if you really want to do that, by using Matlab along with MS Excel, you can model fibers and import the model into the Abaqus. Nevertheless, you should bear in mind that this method will take a very long time to process.
There is no significant difference in stiffness. I suggest keeping your model as homogeneous material!
Mehran Shahpari and Abdullah Sikar Al-Issawi Thankyou for your help. What parameters should I consider specifically while defining material properties for SFRC?
You must conduct stress strain curve, modulus of elasticity, compression and tensile strengths in addition controls each test with respect to fiber ratio.
